PLATEN PRINTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 439,281, dated October 28, 1890.

Application file September 4,1888. Serial No. 284,558. (No model.) Patented in England September 23, 1887, No. 12,891; in France August '7, 1888, No. 192,279, and in Germany December 6, 1889, No. 49,908.

To all whom it may concern.-

Be it known that we, ALFRED Monnrrr, a subject of the Queen of Great Britain, and a resident of Hockley Mill, Nottingham, in the county of Nottingham, England, and CHARLES BUTTERFIELD, also a subject of the Queen of Great Britain, and a resident of 62 Woodhouse Street, Nottingham, in the county of Nottingham, England, have invented new and useful improvements in platen printingmachines for taking off the paper cards, or other material being printed from the platen and delivering the same upon the table in front of the operator and with its printed side uppermost; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the drawlugs and the letters of reference marked thereon, which drawings form a part of this specification.

This invention was patented to us in Great Britain, No. 12,891, dated September 23,1887; in France, No. 192,27 9, dated August 7, 1888, and in Germany, No. 49,908, dated December 6 1889.

This our invention relates to certain new and useful improvements in platen printingmachines, and which invention has for its object to facilitate the taking 0d of the paper, cards, or other material being printed from the platen and to deliver said sheets with their printed sides uppermost upon the table in front of the operator.

We now proceed to describe our said invention, reference being had to the accompanying drawings and the letters of reference marked thereon, similar letters indicatin g like parts throughout;

Figure 1 represents a s1de elevat1on of a platen printing-machine, showing the manner in which our invention is applied thereto. Fig. 2 is a detached elevation of our inven tion separate from the other wellknown parts of the machine, and Fig. 3 1s a plan of same. Figs. 4: and 5 are detail views of portions of the platen, showing the tumbler-cam and connections carrying the oscillating levers, only one of which is shown. Fig. 6 is a detail view of the lifter-bar and the mechanism appertaining thereto. 9 are detail views of the lifter brackets and fingers. Fig. 10is a side elevation of a platen printing-machine, showing a modified form of Fig. 13 is a part side eleva-' Figs. 7, 8, and

thereto. Fig. 16 is an end elevation of Fig. 15.

In the drawings we have shown only such parts of a platen printing-machine as will enable us to describe and illustrate our invention and in what manner the same is operated.

A represents one of thearms, attached to the platen B by means of the stud b and clip I), as shown in enlarged detail in Figs. 4 and 5. Firmly attached to an axle protruding at the extremity of the arm A-is a lever O, which carries at its upper end the lifter-bar D. Hinged or pivoted to the lifter-bar D at d is the rod (1' and lever 01?, the lever d carrying an axle and truck 01 said lever (1 being acted upon by a spiral spring d which keeps it in its normal position. Suitably attached to the lifter-bar D and the hinged or pivoted rod (1 are the fingers d and brackets cl, to which are hinged or pivoted at d the lifters d Fixed to the platen B is a frame E, which is adapted to be moved up or down a slot in the platen, for adjustment, and in which frame E is pivoted a tumbler-cam c, which is formed with a projection e to preventits turning when the truck (1 passes overa projection 6 The truck (1 runs up from the angular position of projection c which causes the fingers d to be opened, and said truck 01 having passed this projection the spring d presses the lever downward, and said fingers are thereby closed. Said truck 01 in its return movement passes under the projection c and the tumbler-cam is turned over on its axis,

so that said truck may pass it without giving motion to the lever. turns back intoits normal position by reason of the weight of the projection e.

The lower end of the lever C has a truck 0, mounted upon an axle, and which truck is kept in close contact with the plain wheel. F by the spring a, coiled around the axle a and having one extremity bearing against a stud or projection a in the arm A and the other extremity bearing against the lever O, as shown at 0 Said lever C also carries a projection 0 which is pushed outward by the adjustable truck g, mounted in the connecting-link G.

A modified form of our. invention is-necessar-y whenitis to be applied to certain platen printing-machines which have the axisof vibration of the platen below'the center of the platen Saidmodificationmaybe described-as follows, referencebeing-had. toFigs. 7 to=l6 of the-drawings,

K. represents a. lever mounted at one end upon a shaft and having at its other end a truck K ,which isadj ustable in the slot K The shaft 70 hasformed upon its circumferenceaflatsurfacele, which is adapted. toreceive thebridge 10 which by means of the set-screw 10. serves to hold the lever L securely tothe shaft is. Coiled around aboss situatedzat; the lower end of the-lever L is a spring Z, one: end of which. bears againsta projectionll" and the other end bears against a bracket Z which carriesthe aforedescr-ibed mechanism. The spring Zhas a constant tendency to keep thev lever inv its outward or backward position against the stop Z and it also servesto keep the truck K against the periphery of the cam'M, or-, as shown in an alternative form, Fig. 13, thetruck- K, mounts edat the end of the lever L against the adjustable mm 9,, carried by the connecting: linkG. Saidcams M and. g impart an oscillating to-and-fro movement to the levers LfandL and levers K and L.

At the upper end of the lever L issuitably hinged atn. the lifter-barN-Qwhich is pressed upward against a stop Z on lever L by the spring Mflone end of which presses against asmall projection on lever L at Z and the other end, against the lifter-bar N.v Suitably attached to the lifter-bar- N isthe lever m, Fig. 14, a1t one end of which is mountedthe truck m which when brought into contact Said tumbler-cam then The cam j servesto raise the with the cam. B, carried by the platen B, causes the lifter-bar N. to be pressed downward. J ournaled to centers or bearings m upon the lifter-bar N is a rod M and lever m having a tail-piece at one end and at its other extremity a truck M The journaled rod M carries the fingers (Z above referred to, and suitably attached to the lifter-bar are the brackets (1 to which are hinged or pivoted at d the lifters d having projections at their inner ends, which are acted upon by spring d Figs. 7, 8, and 9. The fingers d on the hinged rod M in their normal position lie between the lifter-hinges d and press upon the lifters d by thetension of, the spring ,M one end of which bearsagainst the lifterbar N and the other end against the lever m Pivoted in a frame E upon the platen B is the tumbler-cam e, as-in thebefore described construction,

The operation of out said. invention is. as follows: The movement of. the oscill'ating lever L toremove aprintedsheet is intheop: posite directionrtothe platen,and is so timedl that the-truck m shall. pass under the; cam B when t-heplaten hasnearly completed its backward motion. after the impression, has

beentaken and as thelifter-bar. N d'escends to take the sheet,rsaid litter-bar.- being movable-in their'centersr Thefingersand lifters are adjusted to the varying. anglesof the platen. B: by the cam B, which. presses the lifter-bar N in the opposite direction to the tension of. the spring, and. the, lifters arethereby guidedtothepaper to'be picked up. -As thelifter-bar descends, the truck M, carried upon. the lever m passes: over the projection e of the tumbler-cam e, thuscausing the fingers d to be opened, and the lifters (i being freed, fall upon the platenB or blanket, to which they. are kept in close contact by the spring dl By a stillfurther: downward movement of the lifter-bar N said lifters d? are carried under the printed sheet and lift? it betweenthemselves andthe fingers c1 5. At this time the truck M. falls over the end? of the projection e of the tumbler-cam e and the fingers (15, closing upon the lifters d flipushthe inner projections downward, thereby cans: ing the points of thelifters to pickup the printed. sheet from the platen. The fingers d and the lifters d nowv simultaneously close upon it, andthe levers O Lmove backwardto onto the table J at the same time as the levers C and L are completing their outward movement. The stop Z prevents the levers C and L from being carried too far back by the springs c and Z. Our taking-01f mechanism is capable of being wholly thrown out of gear for convenience in making ready, and is, moreover, adjustable so as to take the sheets from various positions of the platen in the direction of its depth, and which adjustment may be effected in one of the following ways: by moving the truck K in the slot K of the lever K, by moving the cam e in its slot, or by moving the cam g in the socket at the end of the connecting-link G. By releasing the set-screw in the bridge 70 or by moving the projection in the clip the taking-oft mechanism may be thrown out of use altogether, and the lifters remain stationary under the shield j and Z and the machine may be used in the usualway without them.

Having now particularly described and ascertained the nature of our said invention, and in what manner the same is to be performed, we declare that what we claim is 1. In a platen printing-machine, the combination of the arm 0, the projection 0 carried by the arm 0, said projection being adapted to engage with the truck g, the truck 0, made to bear against the plain wheel F, and the axle a, all substantially as and for the purposes hereinbefore set forth.
